Just Kristin.

Lachey & Cavallari Meet Again

Last week after Nick Lachey and Kristin Cavallari were spotted together, she said they were "just friends." But they were spotted together again over the weekend, PEOPLE reports in its latest issue.

The pair were seen having a drink together at Stanley's restaurant in Sherman Oaks, Calif. So, is it turning into something more substantial than "just friends"?

"Eventually it might turn into something more serious," a pal of Cavallari, 19, who recently split from reality star Brody Jenner, tells PEOPLE. "But right now it's not. They're at that stage when they're getting to know each other."

That seemed to be what they were doing over drinks. "They were talking to each other. They weren't being overly touchy-feely; he was playing it pretty cool," says a patron standing nearby. "But she was definitely flirting. She was laughing and flipping her hair back. They seemed to be enjoying the conversation."

A buddy of Lachey's admits that Cavallari, who starred in Laguna Beach, "actually is his type: blonde, a little ditzy, a sweet girl. It makes sense, but I just can't imagine he would follow through with it."

According to Cavallari's friend, she and Lachey, 32, "have not hooked up." And a source close to Lachey insists, "Nick's not looking for a girlfriend. He's not exactly healed from (Jessica)."

Besides, on Monday, Lachey began an 11-city radio tour to promote his CD. Says the source: "That's what he's focused on."
